Overview

This report attempts to estimate the rise in tariffs for electricity consumers in Delhi over a period of ten years, and explore the effects of increasing renewable energy penetration on the tariffs.

Estimating the future cost of electricity requires an understanding of the different components that make up an electricity bill, the regulatory procedures and influences that impact the tariff for each of these components, and the market and political forces that affect these tariffs.

The estimates incorporate two scenarios of renewable energy growth (high renewable energy penetration and low renewable energy penetration) and their impact on cost of procurement.
